Abstract
In a charging current method for limiting a charging current in a DC voltage circuit, the charging current is conducted from an electric supply grid into the DC voltage circuit via diodes. A DC voltage of the DC voltage circuit is ascertained and is based on the supply voltage of the electric supply grid. A variable undervoltage threshold on the DC voltage circuit is determined and a limit of the charging current is activated when the DC voltage reaches or falls below the variable undervoltage threshold.
